I built from dovecot-2.2.25.tar.gz on Mac OSX 10.11.15 (El Capitan) the usual way: CFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure make sudo make install sudo /usr/local/sbin/dovecot It consistently crash on startup with the following entries in /var/log/mail.log (edited backtrace): Jul 27 07:39:26 macbook-pro dovecot[70234]: master: Dovecot v2.2.25

Two issues came up for me when building 2.1beta1 on OS X (10.5.8 on PPC). The first was already mentioned in an earlier thread by a BSD user (http://dovecot.org/list/dovecot/2011-September/061201.html). I just wanted to point out that the error is still occurring in spite of a new test for GNU ld in the configure script. I needed to remove "-no-undefined" specifically:

The attached patch should fix the problem with dying imap on "Unrecognized event". The problem is that when we register a handle for IO_ERROR only, we still can get readable/writable event without EV_EOF being set. This case was not handled. -- Vaclav Haisman -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: io-kq.diff URL:

Hi, The sample program given below freezes my 5.1R installation. This program is from a bug report - kern/54331. That bug report (http://lists.freebsd.org/pipermail/freebsd-bugs/2003-July/001608.html) is for the shutdown function call, whereas my machine basically just freezes up and reboots on kevent itself. I am also noticing this problem with another program i wrote (but too long to include

Hi, I would like to submit the attached patch. It implements IO loop using FreeBSD's kqueue/kevent syscalls. It is based on snapshot of CVS HEAD as of 2005-12-12. I could only give it limited testing on FreeBSD 5.4 but it works fine so far.

I rewrote much of the kqueue code since the old code didn't handle properly the case when both input and output I/O handlers were added to the same file descriptor with different callbacks. This is done commonly in Dovecot, so I'm wondering why more people didn't complain about problems with it.. :) I don't anyway have access to any BSDs so the code is completely untested. Please

Some more information: the issue has just occurred, again on an instance without the "service_count = 0" configuration directive on pop3-login. I've observed that while the issue is occurring, the director process goes 100% CPU. I've straced the process. It is seemingly looping: ... ... epoll_ctl(13, EPOLL_CTL_ADD, 78, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=149035320,

Hi there, I get a crash when doing "make check" for version 2.3.0 on Solaris Sparc. The build was done with gcc 7.3.0.

Hello, dovecot crashes when it receives -HUP signal. It happens always if there was some activity - for example, if I start dovecot, check any account through POP3 and then send -HUP to dovecot process, it crashes with the following log entry: segfault at 00000008 eip 0804d3fb esp bfdd3860 error 4 If there were no activity at all since starting, it does not crash. my dovecot -n output: #

Hey, I noticed that there was an ioloop "module" (if we can call it that) for select and poll and decided to add one for kqueue (aka kevent) BSDs high performance descriptor multiplexing API. I haven't done any of the configure glue stuff but the code is complete and works well. kqueue is available on all recent versions of FreeBSD, NetBSD, OpenBSD and Darwin (and therefore MacOS
